我有 tabpanel，其中包含几个选项卡。我将在这里专注于第 6 个选项卡 - navigatingPanels.js 文件。在这个文件中，我有一个卡片布局，以便用户可以填写 form1 并在提交时移动到 form2(滑动到 form2)。我还有一个带后退按钮的停靠工具栏，以便用户可以返回到 form1(如果需要)。它给出了一个错误 -
Uncaught Error: [ERROR][Ext.Base#callParent] Invalid item given: undefined, must be either the config object to factory a new item, or an existing component instance.
可以在这里看到该应用程序 - http://maalguru.in/touch/Raxa-70/MyApp/
更新 - 如果我向相关面板添加一张额外的卡片，并删除 form1 和 form2(必需的面板/卡片)，那么它就可以正常工作。在这种情况下，我必须将 setActiveItem 设置为所需的卡片(form1 和 form2)。更改视口(viewport) - http://pastebin.com/P4k04dBQ 有什么解决方案可以只用 2 个面板/卡来实现吗？
Viewport.js
Ext.define('MyApp.view.Viewport', {
extend: 'Ext.TabPanel',
xtype: 'my-viewport',
config: {
fullscreen: true,
tabBarPosition: 'bottom',
items: [{
xclass: 'MyApp.view.navigatingPanels'
}]
}
});
NavigatingPanels.js
Ext.define('MyApp.view.navigatingPanels', {
extend: 'Ext.Panel',
id: 'navigatingPanels',
xtype: 'navigatingPanels',
config: {
iconCls: 'user',
title: 'Navigating Panels',
layout: 'card',
animation: {
type: 'slide',
direction: 'left'
},
defaults: {
styleHtmlContent: 'true'
},
items: [{
docked: 'top',
xtype: 'toolbar',
title: 'Registeration Form',
items: [{
text: 'Back',
ui: 'back',
align: 'centre',
//back button to take the user back from form2 to form1
handler: function() {
Ext.getCmp('navigatingPanels').setActiveItem(form1);
}
}]
},
form1,
form2
]
}
});
var form1 = new Ext.Panel({
scrollable: 'vertical',
items: [{
xtype: 'fieldset',
title: 'Form 1',
items: [{
xtype: 'textfield',
label: 'Name',
name: 'name',
},
{
xtype: 'button',
text: 'Save Data & move to form2',
ui: 'confirm',
//TODO add some action: to store data
//save data & move to form2
handler: function() {
Ext.getCmp('navigatingPanels').setActiveItem(form2, {
type: 'slide',
direction: 'right'
});
console.log("Form1");
}
}
]
}]
});
var form2 = new Ext.Panel({
scrollable: 'vertical',
items: [{
xtype: 'fieldset',
title: 'Form 2',
items: [{
xtype: 'textareafield',
label: 'Message',
name: 'message'
},
{
xtype: 'button',
text: 'Submit Data',
ui: 'confirm',
//TODO add some action: to store data
//action: 'Submit Data'
}
]
}]
});
App.js
Ext.Loader.setConfig({
enabled: true
});
Ext.application({
name: 'MyApp',
controllers: ['Main'],
launch: function() {
Ext.create('MyApp.view.Viewport', {
fullscreen: true
});
}
});
最佳答案
我终于得到了答案。组件实例不应作为 Ext.define 中的项给出，而应给出它们的配置。 setActiveItem 可以以正常方式调用 -
Ext.getCmp('navigatingPanels').setActiveItem(0);
